Application filed September 6, 1906. Serial No. 333,493.

This invention relates to metallic under 1 frames for railway cars, and more especially to underframes for cars having either a Wooden superstructure, or atleast a wooden floor.

l The object of theinvention is to improve I car underframes of this character in details of construction andarrangement hereinafter described and claimed In the accompanying drawings Figurel is a plan view of the underframe of one half of co the car; Fig. 2 is a side elevation of the same Fig. 3 is a vertical longitudinal section. on the line 3 3 Fig. 1; Fig. 4 is input an end view and inpart a cross section on the line 4-4 Fig. 1; Fi ,5 is in art a cross section on theg line 55 ig. 1, an in part a cross section on the line 66 Fig. 1 and Fig.6 is a perspective view of a draft sill. a

The underframe is provided with center sills 1, shown as rolled channel beams laced 0 'with. their flanges projecting outwar y and extending slightly beyond the. body bolster 2. The. latter isa built-up structure having a center brace 3 between the center sills, and Web members 4 extending. from'the center I sills to the car sides, which in thi case are represented by side sills 5, these a so being of rolledcliannel beams, placed with their flanges projectin' outwardly. The center brace 3 may be'o any desired oonsti'uction,

40 that shown bein two pressed plates placed 1 back to back an havin integral flanges on .top, bottom' and both side edges, the latter being riveted to the webs of the center sills.

A novel featureof this un'derframe is in the web members 4 of the bolsters, which web members are also used in the cross beareor transomsfi, three of which areemployed etween the bod bolsters, the principal feature of said we members also eing used in cross connectors or floor supports? located between the cross-bearers 6 and the bolsters 2. The peculiarity of these web members is the fact that the are. made ofpressed plates havingintegral anges 8 and 9, respectively,

With these cross-bearers or transoms a center on the inner and outer ends as Well as flanges 10 and 11, respectively, on the top and bottom, but the top flange 10 not extending out to the end of the web member, but at the upper edge of said end the Web is left unflanged and projects above the top flange 10, as

shown in the drawings and indicated'by the 7 reference numeral 12. It will be observed that the flanges of these" web members are continuous, except at the upper outerportion thereof. The outer end flanges 9 are riveted directly to the side sills 5, and the vertical web parts 12 extend upwardly above the top edge of the sill and brace the outer end flanges so as to form abutments for a floor stringer 13. The flanges 8 at the inner ends of these web members are riveted directly to the webs of the center sills.

In the body bolsters two'web members of the character described are used, these being placed back to back as shown. At the cross 7 bearers or transoms 6 only a single Web member of the character described isused, and an additional .conneetingpiece or angle 14 is used to connect the outer end to the side sill.

8o brace 15 of pressed metal is placed between i the center sillsi; The cross connectors or floor supports 7 have no center brace in line therewith between the center sills, and these cross connectors also are of much less depth than the web members of the, body bolsters and transoms or cross bearers and also arenot provided with cover plates. They, however, have the same general construction as the web members of the bolsters and tran- 0 some.

The transoms 6 are provided with atop a cover plate 16, and a bottom cover plate 17.

The latter extends underneath the center sills and is'riveted to the bottom flanges 11 9 5, ofythe web members of the transom, while the top cover? plate is riveted to the top flanges 10 and extends through slots 18 in the Webs of the center sills, the latter projecting above the transoms. The bolster also is rovided with a bottom cover plate 19, w ich' extends underneath the center sills and is riveted to the bottom flanges 11 of the web members, and with a top cover plate20, riveted to the to flanges lO'of the web members and exten ing through slots 18 the center sills. The top cover plate is considerably wider than the web members and ex-' tends farther toward'the end of the car than it does toward the center. This projecting art of' the plate is supported by angle rackets 21, riveted to the Webs of the center sills and to the top cover plate.

The underframe described has the center sills considerably higher than the side sills and cross connecting and bearing members, this being for the purpose of receiving the wooden stringers 22, the latter resting upon the bolsters, the cross-bearers or transoms 6 and the cross-connecting floor members 7. The underframe is provided with an end sill 24, which also projects above the tops of the side sills. Stringer supports 25 are secured to the inner face of the end sill, said stringer supports being ordinary angle bars having one flange pro ecting inwardly. At the cormi of the car the side sills and end sill are connected by ordinary angle pieces 26, and a gusset plate 27 is also riveted to the top flanges of the side sills and the stringer suports 25. From this gusset plate a brace ormed of an angle bar 27 extends diagonally inwardly and has its inner end riveted to the top cover plate 20 of the body bolster..

The end sill is shown as a rolled channel laced with the flanges projecting outwardly, ut if desired, it may be of any other construction.

The draft beams are shown at 30, and

' these consist of pressed plates of general 2- shape in cross section, having the top flange.

projecting inwardly and the bottom flange projecting outwardly. The webs of these draft beams are riveted to the webs of the center sills outside of the body bolster. At

their outer ends the draft sills are provided with integral flanges 32 which are continuous with the out-turned bottom flanges and are riveted directly to the web of the end sill as well as to a buffer casting 33, which has a ortion projecting below the bottom edge 0 the end sill,. to which rejecting portion the end flanges of the dra t beams are riveted. The

, center sills are provided with-a top cover plate 36 and a bottom cover plate 37, so that etween the body bolsters said sillis practiminating short of the outer ends ofsaid webs.
